Austin Hobart Clark
Austin Hobart Clark (December 17, 1880 in Wellesley, Massachusetts – October 28, 1954 in Washington, D.C.) was an American zoologist who studied oceanography, marine biology, ornithology and entomology. Personal life The son of Theodore Minot Clark and Jeannette French Clark, Clark obtained his Bachelor of Arts at Harvard University in 1903. He had five children with his first wife Mary Wendell Upham, whom he married on March 6, 1906. Mary died in December 1931 and he married Leila Clark, Leila Gay Forbes in 1933. Career In 1901, Clark organized a scientific expedition to Isla Margarita in Venezuela. From 1903 to 1905, he conducted research in the Antilles. From 1906 to 1907, he led a scientific team aboard the 1882 USS Albatross (1882), USS ''Albatross''. In 1908, he took a post at the National Museum of Natural History, which he held until his retirement in 1950. Clark had important and various roles in a number of learned society, learned societies: he was president o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Evolution
Evolution is the change in the heritable Phenotypic trait, characteristics of biological populations over successive generations. It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. The process of evolution has given rise to biodiversity at every level of biological organisation. The scientific theory of evolution by natural selection was conceived independently by two British naturalists, Charles Darwin and Alfred Russel Wallace, in the mid-19th century as an explanation for why organisms are adapted to their physical and biological environments. The theory was first set out in detail in Darwin's book ''On the Origin of Species''. Evolution by natural selection is established by observable facts about living organisms: (1) more offspring are often produced than can possibly survive; (2) phenotypic variatio ...

Tree Of Life (biology)
The tree of life or universal tree of life is a metaphor, conceptual model, and research tool used to explore the evolution of life and describe the relationships between organisms, both living and extinct, as described in a famous passage in Charles Darwin's ''On the Origin of Species'' (1859). Tree diagrams originated in the Middle Ages, medieval era to represent family tree, genealogical relationships. Phylogenetic tree diagrams in the evolutionary sense date back to the mid-nineteenth century. The term phylogeny for the evolutionary relationships of species through time was coined by Ernst Haeckel, who went further than Charles Darwin, Darwin in proposing Phylogenetics, phylogenic histories of life. In contemporary usage, ''tree of life'' refers to the compilation of comprehensive phylogenetic databases rooted at the last universal common ancestor of life on Earth. Two public databases for the tree of life are ''TimeTree'', for phylogeny and divergence times, and the ''Ope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diagram From Zoogenesis
A diagram is a symbolic representation of information using visualization techniques. Diagrams have been used since prehistoric times on walls of caves, but became more prevalent during the Enlightenment. Sometimes, the technique uses a three-dimensional visualization which is then projected onto a two-dimensional surface. The word ''graph'' is sometimes used as a synonym for diagram. Overview The term "diagram" in its commonly used sense can have a general or specific meaning: * ''visual information device'' : Like the term "illustration", "diagram" is used as a collective term standing for the whole class of technical genres, including graphs, technical drawings and tables. * ''specific kind of visual display'' : This is the genre that shows qualitative data with shapes that are connected by lines, arrows, or other visual links. In science the term is used in both ways. For example, Anderson (1997) stated more generally: "diagrams are pictorial, yet abstract, representatio ...

Starfish
Starfish or sea stars are Star polygon, star-shaped echinoderms belonging to the class (biology), class Asteroidea (). Common usage frequently finds these names being also applied to brittle star, ophiuroids, which are correctly referred to as brittle stars or basket stars. Starfish are also known as asteroids due to being in the class Asteroidea. About 1,900 species of starfish live on the seabed in all the world's oceans, from warm, tropics, tropical zones to frigid, polar regions of Earth, polar regions. They are found from the intertidal zone down to abyssal zone, abyssal depths, at below the surface. Starfish are marine invertebrates. They typically have a central disc and usually five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. Many species are brightly coloured in various shades of red or orange, while others are blue, grey or brown. Starfish have tube fe ...

Crustacean
Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of arthropods that are traditionally a part of the subphylum Crustacea (), a large, diverse group of mainly aquatic arthropods including decapods (shrimps, prawns, crabs, lobsters and crayfish), seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, opossum shrimps, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods (insects and entognathans) emerged deep in the Crustacean group, with the completed pan-group referred to as Pancrustacea. The three classes Cephalocarida, Branchiopoda and Remipedia are more closely related to the hexapods than they are to any of the other crustaceans ( oligostracans and multicrustaceans). The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mulga Parrot
The mulga parrot (''Psephotellus varius'') is endemic to arid scrublands and lightly timbered grasslands in the interior of southern Australia. The male mulga parrot is multicolored, from which the older common name of many-coloured parrot is derived. Taxonomy The mulga parrot was given its current scientific name of ''Psephotellus varius'' by American zoologist Austin Hobart Clark in 1910, after its name ''Psephotus multicolor'' was ruled invalid as the original combination (''Psittacus multicolor'') had been used for another species. Gregory Mathews proposed the name ''Psephotus dulciei'' in 1911 for the same reason, unaware of Clark's proposal, which was published earlier and hence had priority. Mathews described two additional subspecies of mulga parrot in 1912: ''P. varius rosinae'', from a specimen collected from Yorke Peninsula, noting that it had less red on the abdomen and its upper breast was a darker green, and ''P. varius exsul'' from a specimen from Mount Magnet in ...

Dominican Green-and-yellow Macaw
The Dominican green-and-yellow macaw (''Ara atwoodi''), Atwood's macaw or Dominican macaw, is an extinct species of macaw that may have lived on the island of Dominica. It is known only through the writings of British colonial judge Thomas Atwood in his 1791 book, ''The History of the Island of Dominica'': Austin Hobart Clark initially included these macaws in '' Ara guadeloupensis'' in 1905, but upon being referred to Atwood's writings, he listed them as a distinct species in 1908. As no archeological Archaeology or archeology is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology ... remains are known, it is widely considered a hypothetical extinct species. Atwood described a bird which was commonly captured for food and pets. The Dominican macaw probably became extinct in the late 18th or early 19th century ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
